DATA VISUALIZATION

• Originally, visualization was considered a subfield of computer graphics, primarily because visualization uses graphics to display information via images.
• Visualization applies graphical techniques to generate visual displays of data.
• Here, graphics is used as the communication medium

Visualization as part of Graphics

LBRCE

DATA VISUALIZATION

• Beyond the use of graphics, the most important aspect of all visualizations is their connection to data.
• Computer graphics focuses primarily on graphical objects and the organization of graphic primitives; visualizations go one step further and are based on the underlying data, and may include spatial positions, populations, or physical measures.
• Consequently, visualization is the application of graphics to display data by mapping data to graphical primitives and rendering the display.

Visualization as part of Graphics

• The field of visualization encompasses aspects from numerous other disciplines, including human-computer interaction, perceptual psychology, databases, statistics, and data mining, to name a few.
• While computer graphics can be used to define and generate the displays that are used to communicate the information, the sources of data and the way users interact and perceive the data are all important components to understand when presenting information.

Scientific Data Vs Information Visualization

• Although during the 1990s and early 2000s the visualization community differentiated between scientific visualization and information visualization, we do not.
• Both provide representations of data.
• However the data sets are most often different.
